;To all it may Camem- -Be it known that W RIJMZ BARBER,

a citizeiiof the United States, and resident of Stonington, inthe countyof New London and Sta't'e of Connecticut, have invented anism forfeeding 'sheetsito and delivering thereof and improved means for feedingtw slip, sheets for each'revolution of the im-fi pression" cylinder sothat each sheetas'fflitis them. from-an impression cylinder and in themechanism for feeding slip sheets intoposition to be combined with therinted sheets as they are delivered from t'esaid impression cylind'en.

.- My 'nvention more particularly consistsin a mechanism in. whichimproved means are provided 'fo'r -feeding two sheets to the impression"cylinder for each revolution deliveredifrom the impression"cylinder-may have a slip sheet associated therewith before it istransferred to a-sl ieet delivery device.

This invention is shown in connection with a multicolor printing pressprovided with a reciprocating-sheet delivery device but'it is obviousthat the invention could be applied; in connection with printing pressesof other types and in connection with sheet delivery devices of varioustypes.

te 'rvals to receive the slip sheets. and "deliver them to the printedsheettransfer de vice..

Themain frame is denoted by 1, in which?" frame are mountedthe shafts 2,3, 4, 5', of the platecylinders 6, 7, 8, 9, and the shaftoft-heimpression cylinder 11. Suitable inking mechanisms: 12, 13,.-14,15,-are pro- 1 videdfor supplying-inkto the plate cylin'-- ders 6, 7, 8,9. The impression cylinder-11 isprovided with a plurality of sets ofgrippers. In the present instance, two sets of grippers 16,17, are shownarranged dia-' p,

- metrlcallyopposite each other. A stationary cam 18 is provided, whichcam is arranged to :open both sets of grippers- 16, l,7,'at the l propertimes forrec'eiv'ing the'sheets to be printed and for-delivering theprinted sheets to the sheet transfer device to be hereinafter described.

by 19 and its set of grippersby/QQ. The

sheets to be printed may be fed to the grip- I pers 20 from the table21, or from any other suitable source of sheet supply The mechanism forcontrolling'th'e opening and ClOS- the sheet and transfer it to theimpression cylinder 11,'is constructed, arrangeda'nd operated as followsThe shaft of the grip pers 20 is provided withlatumbler .22.t0

which is,appliedi'springs-23, 24; This tum-I bier 22 isoperated upon atthe proper times by being carried by the revolution oft-he feed cylinder19, overpins 25, 26, fixed- =in the'main frame 1. The pin 25 is arrangedto cause the closing oft-he grippers 20, to

engage the. sheets fed fromfthe table 21am 1 i the pin 26' is arrangedto'open the grippers,,,

for transferring the sheets to the grippers' '16, 17, on the impressioncylinder 11.

- The printed sheet .transier,device in the i present i stancecomprisestwfo reels 27,28 provldedfi respectively with sets of grippers29, Azfixed cam 31' is arrangedto open the grippers .29 onthe' firsttransferred 27 for receiving the printed sheets from the inder 11, saidcam being also arranged to 27m the reel28.

.A slip sheet is fed tov the ,printed' sheet transfer device in positionto be combined With each printed sheet,as follows. The

ioe

,sets of grippers 16,117 on the irmression cylopen the grippers 29 fortransferring the .1 U printed sheets from the first transfer reelgrippers. 30 (in the second transfer i 1, v .The main sheet feedcylinder is denoted slip. sheet feed cylinderis' denoted by 32, whichcylinder is provided with a set of grippers 33 arranged to receive theslip sheets from the table 34, or other slip sheet feeding device. Themechanism for controlling the opening and closing of the grippers 33 onthe slip sheet feed cylinder 32,.v

is constructed, arranged and operated as follows. The shaft of, thegrippers 33 is provided with a tumbler 35, to which is ap plied-a spring36. This tumbler 35is op- -'slip sheet to the grippers on the secondtransfer reel 28, of the printed sheet transfer device. ,A fixed cam 39is arranged in position'to first open the grippers.30 to receive theslip sheet and then open the grippers 30 to receive the printed sheetfrom the grippers 29 on the first transfer reel 27 A second fixed cam 40is arranged in position to open the grippers 30 at the proper time fordelivering the combined printed and slip sheets to a sheet deliverydevice of well. known or approved form. In the present instance, I haveshown a reciprocating flat sheet delivery device 41 .having the usualguides 42, 43, and forwarding reels 44, 45, 46. i

A sheet stop 47 is provided for the main sheet feed table 21, and asheet stop is pro vided for the slip sheet feed table 34. These stopsare operated from a cam 49 on the cam shaft 50, as follows. Aspring-pressed rocking lever 51 is provided with a stud roller 52engaging the cam 49. A rod 53 connects this lever 51with an arm 54 fixedto the shaft 55 of the stop. 47. Another spring-pressed lever 56 isprovided with a I stud roller 57 engaging the cam 49, which level isprovided with a rod 58 connected to a rocking arm 59 fixed to th L shaft60 of the stop. 48. j These parts are s 1 timed that the steps 47, 48,will be swung up into position and hold the main sheet and slip sheetuntil their advance edges are to be engaged by the grippers'on the mainsheet feed cylinder and slip sheet feed cylinder respectively.

The geared connection of the several parts is as-follows. A stud shaft61 is mounted in the frame 1, which shaft may be driven at.

the desired speed from any suitable source of power, not shown herein.The impression cylinder 11 is provided with a spur gear 62 fixedthereon, and a loose spur gear 63, which loose gear is driven bya spurgear 64 fixed to the shaft 61, The main sheet feed cylinder 19 isdrivenfrom the impression cylinder 11, through the gears 63, 65. The'firsttransfer reel 27 is driven from the from the second transfer reel 28,through 62, 66. The second transfer reel 28-is driven from the shaft 61,through the gears 64, 67. The slip sheet feed cylinder 32 is driven thespur gears 68, 69. The sheet forwardk ing roll 46 is driven from theshaft 61, through the gears 64, 70. The tapecarrier of the sheetdelivery device 41is driven from the second transfer reel 28,. throughthe gears 68, 71, 72, and the sheet forwarding roll 44 is driven fromthe gears72 by a gear 73. The cam shaft 50 is driven from the secondtransfer reel 28 through. the

gears 67*, 74.- The slip sheet feed .roll 75, which co-acts with thecylinder 32, is driven from the said cylinder through thefspur gears 69,76.- A sheet guide 77 is located in position to guide the printed sheetsaround the first transfer reel 27, and another sheet guide 78 isarranged in position todirect the slip sheets from the cylinder 32 1 tothe second transfer reel 28.

While the present, drawings disclose means for feeding two sheetssuccessively to the'impression cylinder for each revolution thereof, onesheet being delivered for each revolution of. the sheet feed cylinder19, and while the" mechanism isshown for delivering a slip sheet foreach revolution of the slip sheet feed cylinder 32 for combining a slipsheet with each printed sheet delivered fromthe impression cylinder 11,it is to be understood that the impression cylinder may be provided withany number of sets of grippers and means employed for feeding sheets toeach set of grippers and for feed-: ing slip sheets in position to becombined with printed sheets as they are delivered from the impressioncylinder; hence I do not wish to limit myself tosimply the prosvisio'n'oftwo sets of grippers on the-,im: pression cylinder. i

It is to be understood that where the=terms cylinder or reel are used,that I in tend to cover any joperative device [for .carrying the sheetsthrough the prescribed paths' It is also evident that various changesmight be resorted'to in the con struction, form. and arrangement of theseveral parts without departing from the spirit and scope of myinvention hence I db not wish to limit myself strictly to theconstruction herein shown, but V What I claim is: v h 1.
